(from ebookjapan):
Warukaro, a samurai who easily gets into a bad mood, is persuaded by his fearful wife to steal the castle of Shirotori, where the lord of the castle resides. With his brainy son as his brain, and a kunoichi with a knack for disguise as his companion, he executes his plan by any means necessary! Will they be able to take over the castle? A nonsense gag that appeared in "Weekly Shonen Sunday" and "Manga Shonen"! Also includes "MOCTOTUS" from "Gal Life" and "Gag" from "Chuichi Jidai"!
